CARDING MACHINE.

Application filedSeptember 2Q, 1923. Serial No. 663,740.

To all whom t may concern.

Be it known that I, ANDR AUBOURG, a citizen vof the Republic lof France, residing at Roubaix,Department of the Nord, and Republic of France, have invented certain new and useful Improvements in Carding` Machines, of which the following is a. speci- Y fication.

In the production'of textile4 threads of cotton or wool, or wool and cotton, it is` the universal practice to subject the fibres of the materialwhich comprises the sliver from which the thread is spun to theaction of various devices such as carding machines, drawing machines and slubbing frames in order that the fibres of the sliver will exe tend longitudinally thereof and as nearly as possiblek in perfect parallelism. It is well known that the fibres of the slivers obtained from the carding linachine do not extend in parallelism andvconsequently the drawing machines are principally relied upon to produce the desired parallelism of the threads. It has been'recognized that it is very advantageous to produce the desired parallelism of the fibres ofthe sliver as early as possible in the sequence of. operations to which the sliver is subjected, as by so doing a more perfect thread free from loose or floating libres could be produced; While many different devices have been adopted for attachment to the plate in front of the drawing-off rolls of the carding machine, these devices have usually been arranged in such a way that the sliver in its travel from the carding box to the coiler has merely been subjected to some .sort of a frictional effect in order to exert a straightening infiuence upon the bres.

These devices have been far from satisfactory and therefore it is the principal object of this invention to provide a new and improved construction of a device of great simplicity which is adapted to perform the desirable straightening effect upon the fibres of the slivers and which device can be readily attached to a carding machine, a drawing machine or a slubbing frame.

Referring to the drawings- Fig. l shows a plan view of a device embodying my invention. l

Fig. 2 shows a side elevation of the structure shown in Fig. l.

Fig. 3 is a side elevation of the funnel usually attached to the carding machine plate yand through which the libres are passed from kthe carding rolls to form the sliver, and Y Fig. 4 is a cross section through a funnel as shown in Fig. 3 attached to a carding machine plate iny combination with the de* vice shown in Figs. l and 2, the device acting as a lock-nut for the funnel, and illustrating the passage ofthe sliver through the device.

As shown in Figs. 1 and 2 of the drawings, my improved attachment consists of a ring A of any suitable material, such yas brass and having a portion B thereof in the shape of a truncated cone. The portion B is provided with a plurality of grooves or apertures of suitable shape in each of which is adapted to be received a pin C, the pins C being secured within the grooves either by a able manner. The ring A is internally screw threaded -to engage upon the threaded end D of the funnel D and acts as a lock nut for the funnel when thersame is secured upon the plate E (see Fig. 4) of the carding machine. Y

It will be noted that thepins C converge towards the axial linel of the ring to form a cone-shaped comb-like structure, the teeth of which as shown in Fig. 4 extend substantially to the center of the sliver F as it passes from the machine, the distance between the inner edges of the pins varying from l to 3 millimeters according to the size of thread desired.

ImaZZm/zon cmd operatz'on'of the device.

In installing the deviceI 0n a carding machine a ring A provided with the pins C is either screwed directly onto the funnel D as shown in Fig. 4 on the plate of thev carding machine in front of the calendar or drawoff rolls, the ring serving as a lock nut for In installing the device upon a drawing machine the ring is secured in a manner similar to that just described, upon the funnel of each drawing head, its operation being similar with the drawing machine to its operation with a carding machine.

The sliver obtained by the use of my device is of an entirely different appearance to the slivers obtained in the usual way as it Vpossesses greater brilliancy, is more glossy and silk like, more round and uniform. and is entirley free from loose or loating7 fibres.

For the same weight its volume is very greatly reduced and the capacity of a can is increased 20%. From this there results a great saving` of labor formerly required for replacingthe cans of the carding, drawing and slubbing machines. Furthermore, the sliver will pass through all of the various machines in an absolutely perfect manner, and finally the thread obtained is not only more uniform, more round and has fewer loose libres, but what is of even more iniportance, experiments have shown an increased strength in the thread of from 10 TWhile I have shown the ring as provided with eight of the pins C, it will be obvious that any desired number of pins could be employed and that the size, sha-pe and relative arrangement of the pins may be varied without departing from the scope of -my invention. YVhile I have used the term pins to designate the members C, such term is not to be construed as limited to a thin cylindrical member, but is intended to cover any type of a tooth like structure capable of performing a combing action.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. In combination, a device adapted to be attached to a carding or drawing machine and for straightening and combing into substantial parallelism the libres of a sliver, said device comprising a plurality of comb teeth constructed and arranged to project into the libres of said sliver adjacent the centre. thereof, and to perform a combing action on the sliver in its travel through the machine, and a funnel through which the sliver is fed before reaching said teeth.

2. A device adapted to be attached to a carding or drawing machine and for straightening and combing into substantial parallelism the ibres of a sliver, said device comprising a plurality of comb teeth constructed and arranged to form a truncated cone structure and to project into the libres of said sliver adjacent the centre thereof, and to perform a combing action on the sliver in its travel through the machine.

3. A device adapted to be attached to a carding or drawing machine for straighteir ing and combing` into substantial parallelism the libres of a sliver, said .device comprising a plurality of comb teeth constructed and arranged to forni a truncated cone structure, the opening of the smaller end of which varies from 1 to 3 millimeters according to the size of the thread desired and said comb teeth adapted to project into the libres of said sliver adjacent the centre thereof, and to perform; a combing action on the sliver in its travel through the machine.

In testimony whereof I have affixed my signature.
